Looks like this morning's BOS-OAK is doing it again (stop in DEN)...
I hope they warn the passengers before boarding! I flew BOS-SFO recently nonstop (on another airline) specifically because I had a very bad cold and couldn't handle more than one cabin pressurization/depressurization event. (Actually I could barely handle that; I haven't been able to hear much since returning from that trip.) I'd be none too pleased to find out about an enroute stop after departing.
